Its a little late but...I recently took my 2000 S in for a cracked coolant tank, after finally convincing the technician it was actually leaking, the said they replaced the tank. I picked my car up about 5:00 on Friday and drove home (8 miles). My wife is going out with a friend so she takes the car and on her way home she tells me the red light on the temp gauge is blinking (Frankly, I am shocked she noticed). She verified the temp was still normal so I told her to continue home (2-3 miles). When she got back sure enough the coolant level was at the bottom of the tank. I know I may be the victim of an idiot mechanic but after seeing some of the recent posts on some quality issues, it makes me wonder.....I had a Miata for 15 years drove it all over and autoX'ed it quite a bit...and besides tires It was in the shop 1 time (timing belt)...I'm looking at two times this week..
